Products Overview

EPI develops, manufactures, distributes and sells: (a) degradable and biodegradable chemical additives to manufacturers of finished plastic products in the packaging, agricultural and composting industries, among others, and (b) degradable landfill cover and wrap systems to customers in the solid waste management industry. The principal chemical additives sold by EPI are proprietary oxo-biodegradable plastic additives, Totally Degradable Plastic Additives® (TDPA®).

TDPA® is added in typically small quantities of 2 to 3% to commodity resins (polyethylene, polypropylene and polystyrene) during the manufacture of finished plastic products, using standard manufacturing equipment and processes. It causes the plastic to degrade at a controlled rate when the plastic is exposed to photo (sunlight), thermal (heat) and/or mechanical stress and, in the case of polyethylene products (such as grocery, shopping and garbage bags), TDPA® causes the plastic to ultimately biodegrade. Plastic incorporating TDPA® is cost-competitive. It is virtually indistinguishable in appearance and performance from traditional non-degradable plastics until degradation of the product is triggered in accordance with end-user requirements (following its “shelf” or “service” life).

TDPA® is currently marketed in over 70 countries through a network of licensees, sales agents and distributors. Significant end-users of shopping and garbage bags manufactured with TDPA® include Tesco PLC, the world’s third largest supermarket retailer, Migros and Exito. EPI's degradable landfill covers (Enviro Cover), which are manufactured using TDPA®, are sold to some of the largest landfills in the world. For example, Puente Hills Landfill in California, which is the largest landfill in the United States, is using Enviro Cover

Additives for Biodegradable Plastics

TDPA Oxo-biodegradable AdditiveBecause traditional plastics are very stable and not readily degradable and biodegradable in the environment, discarded plastics represent a significant environmental problem, both as litter and as solid waste in landfills. As litter, disposable plastic products (in particular, plastic bags) are a visible and widespread pollutant, and a threat to animal and marine species and to human health. In landfills, they add to landfill volume, hinder landfill compaction and delay the biodegradation of discarded organic materials, thereby fostering the formation of methane, a harmful greenhouse gas. Plastics that would degrade and biodegrade relatively quickly to non-toxic end products in these disposal environments would be a welcome step in managing these issues.

Over the last two to three decades, companies in the plastics industry have developed various approaches to make degradable and biodegradable plastic products that process and perform equivalently to inexpensive and widely-used commodity plastics. The intent has been to develop a degradable and biodegradable plastic that is as functional as commodity plastics, but that would degrade and biodegrade relatively quickly in a disposal environment (litter, landfill, compost, water soil). EPI’s proven TDPA® technology is the most practical and economical way available today to accomplish these objectives.

Biodegradable additive TDPA®, when added in small quantities to the most common and widely used commodity resins during the manufacture of finished plastic products, causes the modified plastic to degrade at a controlled rate. The degradation, which involves the reaction of the plastic with oxygen in the air, is initiated by exposure to ultraviolet light (sunlight), elevated temperatures and/or mechanical stress. It is “programmed” to start degradation on disposal after the product has fulfilled the required shelf and service lives as defined by end users. Products made with polyethylene (such as grocery, shopping and garbage bags), have been shown to subsequently be biodegradable into non-toxic end products.

Biodegradable plastics incorporating TDPA® is processed, performs and are visually indistinguishable from conventional non-degradable plastic materials. They are cost-competitive. They are also compatible with existing recycling operations and can be safely co-mingled with conventional plastic inputs prior to the onset of degradation.

TDPA® biodegradable plastic products are food contact compliant and meet applicable US, Canadian and European standards. The compliance is supported by scientific testing and published test reports that enable EPI to provide legitimate environmental claim statements. Published work has also demonstrated that composts made from plastics incorporating TDPA® has no toxic effect on sensitive plant or animal life.

Manufacturing & Warehousing

EPI manufactures and uses custom compounders that are ISO 9000 certified in the UK, USA and Canada to produce its TDPA® additives, which are incorporated into traditional plastics to make them degradable and biodegradable. EPI has warehousing facilities in North America, Europe and Asia for ‘JIT’ distribution.

Distributors & Agents

TDPA® additives are marketed by EPI directly and through a network of licensees, sales agents and distributors in over 70 countries. EPI does not generally sell products to retailers or end users but rather licenses additive packages to manufacturers that supply finished products to retailers and end users.






A carbon footprint is "the total set of greenhouse gas (GHG) emissions caused by an organization, event, product or person.” Greenhouse gases can be emitted through transport, land clearance, and the production and consumption of food, fuels, manufactured goods, materials, wood, roads, buildings, and services.

For simplicity of reporting, it is often expressed in terms of the amount of carbon dioxide, or its equivalent of other GHGs, emitted.

The concept name of the carbon footprint originates from ecological footprint discussion. The carbon footprint is a subset of the ecological footprint and of the more comprehensive Life Cycle Assessment (LCA).

An individual's, nations, or organization's carbon footprint can be measured by undertaking a GHG emissions assessment. Once the size of a carbon footprint is known, a strategy can be devised to reduce it, e.g. by technological developments, better process and product management, changed Green Public or Private Procurement (GPP), carbon capture, consumption strategies, and others.

The mitigation of carbon footprints through the development of alternative projects, such as solar or wind energy or reforestation, represents one way of reducing a carbon footprint and is often known as Carbon offsetting

The main influences on carbon footprints include population, economic output, and energy and carbon intensity of the economy.

These factors are the main targets of individuals and businesses in order to decrease carbon footprints. Scholars suggest the most effective way to decrease a carbon footprint is to either decrease the amount of energy needed for production or to decrease the dependence on carbon emitting fuels.
